Abstract: III–V semiconductor nanolight sources with deep-subwavelength dimensions (≪1 μm) are essential for miniaturized photonic devices such as nanoLEDs and nanolasers. However, these nanoscale emitters typically suffer from substantial nonradiative recombination at room temperature, resulting in… read more here.
